黄土地区某高速公路段滑坡机理的现场试验研究

Field test study on landslide mechanism of a highway section in loess area

为判断滑坡稳定状态和了解工程实施后边坡的变化特征,针对黄土地区某高速公路滑坡段,根据有关规范及该项目实际工程地质特征,结合现场情况采用多种监测方法相结合的监测措施,对滑坡深部位移以及地下水位进行详细监测,其中数据采集方式分为人工采集和全自动化采集两种。试验结果对变形发展和变形趋势作出预测,为优化设计、施工提供科学依据。

To judge the stability state of the landslide and understand the change characteristics of the slope after the implementation of the project,according to the relevant specifications and the actual engineering geological characteristics of the project,combined with the site conditions,this paper adopts the monitoring measures of combining multiple monitoring methods to monitor the deep displacement of the landslide and the groundwater level in detail.The data collection methods are divided into manual collection and full-automatic collection.The test results predict the deformation development and deformation trend,and provide scientific basis for optimal design and construction.
